摘　　要：大量的浆砌片石挡墙需要作快速质量检测,作者比较了利用弹性波速、瑞利面波和弹性波频谱分析法后,认为后者分辨率高,方法简单,并作了几百个点的检测,得到了成功。There are much more retaining wall made of mortar and stones in railway lines, road lines and the other engineering objects. How to examining their quality? The author had test the velocity of elastic reflection wave, Rayleigh surface wave method and Comparing the spectrum of frequency of elastic reflection wave, and had elected comparing the spectrum to examining retaining wall for 5 km in length, because this method have some specialties ,such as high resolution, non-interference from materials of mortar and stones, and easiness getting the data.
